3-Flute CountersinksFor the carbide family of these tools, the three-flute represents the ideal “general purpose” countersink. They have enough chip clearance in the three-flute design for a variety of ferrous and non-ferrous materials, while providing enough strength with the radial relief design to attack hardened materials up to 40Rc.

KEO 6-flute line of countersinks are companions to our single flute countersinks and our 3- and 4-flute center reamer line. As a rule, the more edges per revolution, the greater amount of material that may be removed. We have designed the 6-flute tools with staggered cutting edges. See page 46 for set information.

Speed and Feed figures suggested should be considered starting points only.

Speed: Factors affecting optimum Drill speeds depend on: Depth of hole, hardness of material, coolant, drill machine type, hole finish, and hole location.

Feed: Factors affecting feed rates are drill diameters, machinability of material, and depth of hole. Small drills, harder materials, and hole depths in excess of 3 – 4 times diameter require adjustment to suggested drill feed rates.

WARNING: Rotary tools can shatter under improper or severe use. Persons in the vicinity of their use should be instructed to wear safety equipment.

Climb MillingIn conventional milling, the cutter revolves opposite to the direction of table feed. Therefore the width of the chip starts at zero and increases to a maximum at the end of the cut. This can lead to accelerated tool wear under some conditions - conventional milling is recommended for hot rolled steel, surface hardened materials and steels with a surface scale. In climb milling, the cutter revolves in the same direction as the table feed. The tooth meets the work at the top of the cut, producing the thickest part of the chip first. In horizontal applications the resultant force created by climb milling can act as a clamping force, acting toward the machine table. It is important to make sure that the machine tool has no leadscrew backlash. Normally climb milling improves product surface finish and increases tool life.

Speeds and FeedsModern milling cutters capable of operating at higher feeds and speeds, and moving more cubic inches of metal per minute, require greater machine rigidity and more power. Therefore it is important to determine that enough power is available to handle the desired depth and width of cut at the higher feeds and speeds.

Advantages of Climb MillingLonger Tool Life: Since the chips produced are deposited behind the cutter, tool life can be substantially increased.

Ease of Fixturing: Climb milling exerts a downward clamping force on the workpiece and not an upward force as in conventional milling, which results in simplified fixturing.

Improved Surface Finish: Since the chips are not carried by the cutter, less likelihood of marring the machined surface.

Lower Power Requirements: A higher rake angle can be utilized, lowering power consumption.

Better Chip Evacuation: Easier and faster chip removal since chips are deposited behind the cutter.
